Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer in adults. One of the most strongly correlated factors predicting outcome is the presence or absence of vascular invasion. Since microvascular invasion cannot be found with conventional CT or MRI examination, we investigated whether slip-interface imaging (SII) could identify HCC microvascular invasion. The results showed that in 32 of 33 patients with HCC, SII-assessed microvascular invasion agreed with pathology, indicating that this technique may become useful for detecting HCC microvascular invasion and guiding treatment planning.
